Cusco Power Trunk Brace 15+ Subaru Impreza / WRX / STI

Cusco’s Power Brace series is engineered to deliver uncompromising chassis rigidity and cornering precision by reinforcing high-flex zones throughout your vehicle’s underbody. Each brace is strategically designed to reduce unwanted chassis deflection under load, translating to sharper turn-in, more responsive steering feel, and greater confidence at the limit.

From front member braces to rear side bars, floor center reinforcements, trunk bars, and everything in between, Cusco’s Power Brace lineup targets key stress points where body flex typically robs a car of its true handling potential. These aren’t just generic add-ons — they are chassis-specific components, CAD-designed to fit with factory precision and engineered to function in harmony with your suspension system.

Every Power Brace is made in Japan from lightweight, high-tensile steel and finished in Cusco’s iconic metallic blue powder coat for corrosion resistance and visual appeal. Because the braces tie directly into existing structural or subframe mounting points, installation is straightforward with no cutting or modification required on most models. The result is a dramatically stiffer, more connected driving experience — one you can feel from the first turn of the wheel.
